        소형렌즈 성형시스템 개발 및 힘제어에 관한 연구

        국금환(Gum-Hwan Kuk),정동연(Dong-Yean Jung),김갑순(Gab-Soon Kim) Korean Society for Precision Engineering 2008 한국정밀공학회지 Vol.25 No.2

        This paper describes the development of a small lens molding system for manufacturing the small lens like lens of a cellular phone, a small digital camera and so on. In order to manufacture a small lens, firstly, the raw material for lens with spherical shape should be manufactured by processing a glass material, secondly, the mold inserted the raw material for lens should be heated till its molding temperature in the electric furnace, finally, the small lens is manufactured by applying the force using pressuring control system. In this paper, the small lens molding system with the function on force control and velocity control was developed. It is composed of an electric furnace and its temperature control system, a pressuring control system, a body, and so on. The temperature characteristic test of the electric furnace, the force and velocity characteristic test of the pressuring control system were carried out. It was confirmed that the developed system had good functions for manufacturing a small lens.
